• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 7 x 3/4" zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The thread forming Type A/AB design eliminates the need for tapping operations by cold-forming mating threads directly into the base material, creating stronger connections than conventional thread-cutting screws. The Phillips pan head configuration ensures flush mounting while providing sufficient drive torque capacity for production environments. With fully threaded shanks and precision right-hand threading, these screws deliver maximum pull-out resistance in materials up to 0.025" thickness, making them ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment assembly where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These tapping screws feature a No. 7 screw size with 3/4" length and 0.151" thread diameter with 16 threads per inch. The thread forming Type A/AB design conforms to industry standards for sheet metal fastening applications. Manufactured from zinc-plated steel with Phillips drive (No. 2 size) and pan head style (0.296" diameter), these screws are designed for use with No. 30 drill bits (0.1285" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and suitability for global industrial markets.
